Abstract
The utility model relates to an operation mechanism for an isolated switch, which uses a series excitation A. C. and D. C. motor to drive a gear mechanism, the gear mechanism drives a worm mechanism, then the motion is transmitted to a worm wheel, and uniform motion is converted into variable motion through a connecting rod mechanism. The operation mechanism for the isolated switch is characterized in that the time of the close and open switch of the control isolated switch is only 2 seconds, which can reach the position exactly without impact and prolong the life of the switch.
Description
The utility model belongs to a kind of isolating switch operating mechanism.
At present, the isolating switch operating mechanism of domestic use generally all is movement at the uniform velocity, not only all has impact a whole story in motion, and control switch to put in place be by travel switch or clutch.Because travel switch is regulated inconvenience, response speed slow (because of being mechanical action, the operating mechanism on/off switch time reaches 4 seconds) during clutch on-off.Therefore, be difficult to guarantee that by travel switch and clutch switch accurately puts in place.
The purpose of this utility model promptly proposes a kind of speed change output mechanism at above-mentioned weak point, and the position of this operating mechanism can be regulated with control circuit.
The utility model has the advantages that mechanism's on/off switch speed only 2 seconds, and be 1/2 of the existing deciliter time.In motion output speed at the whole story is zero, does not have and impacts.During combined floodgate, speed is by accelerating slowly, and behind the combined floodgate, speed is then gradually by slack-off soon.Adopt this mechanism can reduce arcing and burn out switch contact.In position control system, be provided with the position conditioned circuit specially, adjust operating mechanism outage back stop position.Because electric adjusting is more convenient than mechanical adjustment, therefore, when installing and using, positioning flexibly at any time.
Concrete structure of the present utility model is provided by the following drawings.
Fig. 1 is a mechanical structure schematic diagram of the present utility model.
Fig. 2,3 are electric control theory figure of the present utility model.
(1) series excitation universal motor among Fig. 1, (2) are pinions, and (3) are gear wheels, and (4) are worm screws, and (5) are worm gears, and (6) are cranks, and (7) are connecting rods, and (8) are rocking bars.
The utility model is to realize like this. As can be seen from Figure 1, the utility model mainly is Formed by gear mechanism, worm-and-wheel gear, quadric chain. During work, motor driven gear mechanism, gear (3) drives worm screw (4), then motion is sent to worm gear (5), by quadric chain variable motion is changed in movement at the uniform velocity.
Electric control theory among Fig. 2 is: during machine operation, to the capacitor C charging, during the motor outage, capacitor C is given stator winding excitation as field power supply, makes motor produce a braking moment, and gauge tap puts in place. ZJ among Fig. 2,31、ZJ
2Being contactor often opens and normally closed interlock. Electric control theory among Fig. 3 is: during machine operation, and time relay coil work, normally open contact S closes. When motor cut off the power supply, stator winding excitation was given in the time relay normally open contact S disconnection of delaying time simultaneously, makes motor produce a braking moment, and gauge tap puts in place. Regulate the R of Fig. 32Resistance value can change the exciting current size, thereby switch is accurately put in place.
Claims (3)
1, a kind of isolating switch operating mechanism, the order of connection is in whole operating mechanism: motor connects with pinion is coaxial, gear wheel connects with worm screw is coaxial, and crank connects with worm gear is coaxial, and rocking bar is an output, motor is a power intake, mechanism belongs to space mechanism, it is characterized in that by series excitation universal motor driven gear mechanism, and gear mechanism drives worm mechanism, pass motion to worm gear then, movement at the uniform velocity is become variable motion by linkage.
2, isolating switch operating mechanism according to claim 1 is characterized in that in the braking circuit, and capacitor C is in parallel with stator winding.
3, isolating switch operating mechanism according to claim 1 is characterized in that braking circuit uses normally open contact S control excitation time, and relay coil J is in parallel with stator winding.
